Ex4200 Switches - Juniper EX4200 Hardware Manual

Support for Virtual Chassis—EX4200 switches support Virtual Chassis technology. You can interconnect
up to 10 EX4200 switches to form a Virtual Chassis and manage and operate them as a single network
entity.

EX4200 Switches

Juniper Networks EX4200 Ethernet Switches provide connectivity for medium- and high-density
environments and scalability for growing networks. These switches can be deployed wherever you need
high density of Gigabit Ethernet ports (24 to 480 ports) or redundancy. Typically, EX4200 switches are
used in large branch offices, campus wiring closets, and data centers where they can be positioned as the
top device in a rack to provide connectivity for all the devices in the rack.
You can connect individual EX4200 switches together to form one unit and manage the unit as a single
chassis, called a Virtual Chassis. You can add more member switches to the Virtual Chassis as needed, up
to a total of 10 members.
EX4200 switches are available in models with 24 or 48 ports with either all ports equipped for Power over
Ethernet (PoE/PoE+) or only 8 ports equipped for PoE. All models provide ports that have
10/100/1000Base-T Gigabit Ethernet connectors and optional 1-gigabit small form-factor pluggable (SFP)
transceivers, 10-gigabit small form-factor pluggable (SFP+) transceivers, or 10-gigabit small form-factor
pluggable (XFP) transceivers for use with fiber connections.
Additionally, a 24-port model provides 100Base-FX/1000Base-X SFP ports. This model is typically used
as a small distribution switch.
All EX4200 switches have dedicated 64-Gbps Virtual Chassis ports (VCPs) that enable you to connect the
switches to each other. You can also use optional uplink module ports to connect members of a Virtual
Chassis across multiple wiring closets.
To provide carrier-class reliability, EX4200 switches include:
Dual redundant power supplies that are field-replaceable and hot-swappable. An optional additional
connection to an external power source is also available.
A field-replaceable fan tray with three fans. The switch remains operational if a single fan fails.
Redundant Routing Engines in a Virtual Chassis configuration. This redundancy enables graceful Routing
Engine switchover (GRES) and nonstop active routing (NSR).
Junos OS with its modular design that enables failed system processes to gracefully restart.
EX4200 switches have these features:
Run under Junos OS for EX Series switches
Have options of 24-port and 48-port models
